In-Ear Quad Armature Driver Headphones with In-line Mic & Control

Featuring quad balanced armature drivers specially designed for the LS “Live Sound” Series, the Audio-technica ATH-LS400iS Earphones deliver clear, immersive audio with full, powerful bass. Each housing contains one mid-frequency and one high-frequency driver, along with two low-frequency drivers, resulting in incredibly well-balanced sound across the entire frequency range, and including strong, fully realized bass.

The housings are constructed of rigid stainless steel and tough Tritan resin to reduce unwanted resonance while also providing sleek, see-through styling. Specially designed acoustic sound pipes, fashioned from stainless steel and high-durability resin, are encased within the eartip posts, guiding music from the drivers to the listener’s ears with improved high-frequency response. The eartip posts are angled for a comfortable, sound-isolating fit.

The Audio-technica ATH-LS400iS Earphones comes with a detachable 1.2 m (3.9') cable with A2DC (Audio Designed Detachable Coaxial) connectors at the headphones for exceptional durability and audio performance. The cable is equipped with an in-line mic and controller for handling phone calls and music and video playback on compatible devices. The flexible memory cable loops around the ears for a custom fit that is enhanced by the four sizes (XS, S, M, L) of included eartips.

The AT-WLA1 wireless headphone adapter cable utilizes Bluetooth® technology to turn wired in-ear headphones into wireless headphones. The cable works with any in-ear headphones equipped with A2DC (Audio Designed Detachable Coaxial) cable connectors.

The AT-WLA1 features an in-line mic and controls, allowing you to answer calls, adjust volume and control music playback on compatible smartphones and other devices. The cable’s behind-the-neck design conveniently situates the mic and controls for easy access and places the battery case on the upper back where, if desired, it can be attached to your shirt collar with the included clip. Ear hooks are also included for use with headphones designed to wrap around the ears.

The internal battery powers the headphones for up to 7 hours (200 hours standby) and can be recharged with the included 30 cm (1') USB charging cable.
